Concentrated vulnerabilities in bees: Diet specialists have smaller geographic ranges

open access: yesInsect Conservation and Diversity, EarlyView.
Niche breadth theory predicts a positive association between range size and diet breadth, which could concentrate risk among specialists, but this is not well established for bees. Using global occurrence data (range size) and natural history collection‐derived pollen data (diet breadth), we compared these traits in 633 species from six families and ...

Dust in active nuclei. II. Powder or gravel? [PDF]

open access: yes, 2000
In a companion paper, Maiolino et al. (2000) presented various observational evidences for "anomalous" dust properties in the circumnuclear region of AGNs and, in particular, the reduced E(B-V)/N_H and Av/N_H ratios, the absence of the silicate ...

Winners and losers in subarctic moth communities in a changing climate: Marine regime shifts as predictors for terrestrial insect biomass

open access: yesInsect Conservation and Diversity, EarlyView.
1972–2017, the total moth biomass ina subarctic community had a positive trend but biomass trends differ betweenmoth groups based on taxonomy, phenology and resource use. In the northern latitudes,outbreaking species impact greatly moth biomass Moth biomass is associated withtemperature variables and marine Regime shifts, which can be effective ...
